how to use componentone c1printdocument in asp.net for reading text file and convert into pdf with format? - pdf

Question

I am using the C1PrintDocument class to read a text file and convert into pdf in web. Actually it converts into pdf but without the format as like in text file.
For eg. I have a text file which has only one page. But it makes into two pages while convert into pdf. Below is the code what I use.
Imports System.IO
Imports C1.C1Preview
Imports C1.C1Pdf
Imports C1.Web.Wijmo.Controls.C1ReportViewer
Imports System.Runtime.Serialization.Formatters.Binary
Imports C1.C1Pdf.PdfDocumentInfo
Imports C1.C1Preview.C1PrintDocument
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs)
Handles Me.Load
Try
Dim strmappath As String = System.Web.HttpContext.Current.Server.MapPath("~")
Dim filename As String
filename = Path.Combine(Server.MapPath("~"), "12214.txt")
Dim sr As New System.IO.StreamReader(filename, System.Text.Encoding.UTF8)
Dim str As [String] = sr.ReadToEnd()
Dim doc1 As C1PrintDocument = C1ReportViewer.CreateC1PrintDocument()
Dim doc As New C1PrintDocument
doc.Pages(1).PageSettings.TopMargin = 0
doc.Pages(1).PageSettings.LeftMargin = 0
doc.Pages(1).PageSettings.RightMargin = 0
doc.StartDoc()
Dim overlay As New RenderArea()
overlay.Width = "100%"
overlay.Height = "100%"
overlay.Style.Borders.All = LineDef.Default
doc.PageLayout.Overlay = overlay
Dim lines As String() = System.IO.File.ReadAllLines(filename)
Dim linecnt As Integer = System.IO.File.ReadLines(filename).Count
Dim strpages1 As String()
ReDim strpages1(Math.Abs(linecnt / 66) - 1)
Dim intcnt As Integer
Dim intlinereadcnt As Integer
intlinereadcnt = 0
intcnt = 0
intlinereadcnt = 0
For Each line In lines
If intcnt <= 66 Then
If intcnt <> 66 Then
strpages1(intlinereadcnt) = strpages1(intlinereadcnt) &
line & vbCrLf
End If
intcnt = intcnt + 1
ElseIf intcnt = 67 Then
intlinereadcnt = intlinereadcnt + 1
intcnt = 0
End If
Next
Dim strPages As String() = str.Split(Chr(12))
Dim strPage As String = String.Empty
Dim txtPage As New C1.C1Preview.RenderText(doc)
With doc
.AllowNonReflowableDocs = True
For Each strPage In strpages1
If strPage.Length > 0 Then
txtPage.Text = strPage
txtPage.X = 150
doc.Style.TextColor = Drawing.Color.Blue
.RenderBlockText(txtPage.Text)
.Style.WordWrapMode = False
.NewPage()
End If
Next
End With
Dim m_pdfExporter As C1.C1Preview.Export.PdfExporter
m_pdfExporter = C1.C1Preview.Export.ExportProviders.
PdfExportProvider.NewExporter()
m_pdfExporter.Document = doc
m_pdfExporter.Export(Server.MapPath("~") & "12214" & ".pdf")
Dim sr2 As System.IO.MemoryStream
sr2 = New MemoryStream
doc.Save(sr2)
Dim biteArray As Byte() = New Byte(sr2.Length - 1) {}
sr2.Position = 0
sr2.Read(biteArray, 0, CInt(sr2.Length))
'm_pdfExporter.Export(Path.GetTempPath & "\" & "12214" & ".pdf")
Response.Clear()
Response.Charset = ""
Response.Cache.SetCacheability(HttpCacheability.NoCache)
Response.ContentType = "application/pdf"
'Response.BinaryWrite(biteArray)
Response.AddHeader("Content-Disposition", "attachment;filename=" & "12214" & ".pdf")
Response.BinaryWrite(System.IO.File.ReadAllBytes(Server.MapPath("~") & "12214" & ".pdf"))
Catch ex As Exception
End Try
End Sub

Answer 1

Try using c1PrintDocument1.Export("filename.pdf", true) instead.
